So finally I settled on a make over to a short jacket for spring using a freebie pattern I had. This will be a good alternative to a cardigan.
there was plenty of material to play with when I put the pattern against the suit.
It may not get many wears, but at least it will come out of the cupboard! And I learnt a lot about fabrics used commercially which while looking great in the original were actually a rubbish fabric for home sewing! I was reading some sewing blogs that make-over clothes and it is not an immediately easy way to save money.
